No, it's your fault for accepting it, and assuming they will do nothing the next time, and allowing them to do nothing with no consequences.
Now they are seeing consequences. A 15 term do-nothing Rep was just beaten in the primaries by a KID! And there is a lot more of that going on, and it has become apparent to EVERYONE that we are on a new path.
You can be part of the old, weak, cowardly Democratic establishment, and help them crush this new trend, or you can get on board and give it more fuel.
If you don't, then yeah, whatever bad happens is your fault.
